Hi,

I have a query about the file wrapper.exe and would like to know if anyone knows anyting more about it in this particular context. There doesn't seem to be a huge amount about it on google.
I recently ran netstats -b from the command line to see if I had any suspicious looking connections listing. There was one which I don't know if it is valid or not. It is called wrapper.exe .
In the netstats the foreign address is localhost:1026, the status is establised. I have heard that it could be a maya file, a java related file or malware.
In my computer search two files with wrapper.exe come up. One is from Maya and the other is in the C:/Windows Prefetch folder. The maya one says it hasn't been modified for years so it may be nothing to do with that. The other file in the prefetch folder has been modifed within the last few minutes.

The C:/Windows file's full name is WRAPPER.EXE-001E7F5C.pf and it is 7kb. Both have been scanned with AVG free and spybot which say that there are no threats.

Is it possible from the above information to tell if the wrapper.exe mentioned in my netstats is a genuine window or java function or whether it is malware? I am using Sony VAIO notebook with Windows XP and Internet explorer.

Would really appreciate any help or feedback with this.

Thanks
James

Hello that file has several uses some legit as in a Java function.. If you have Maya accounting it is from that.
The non malware location..is C:\Windows\System32 for Windows XP and Vista

Run this scan and post a log

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Thanks for your reply. I'll do the scan with malware.

There does not seem to be a wrapper.exe in the C:\Windows\System32 . The file that came up when I checked was in Windows\prefetch folder. You stated that the non malware location should be the system 32 folder. Does this suggest that the file in prefecth is suspicious or are there valid wrapper.exe files that can be in there.

To make things stranger I did another search today for wrapper.exe files and the wrapper.exe in the prefecth folder did not appear. I looked in the prefetch folder and the file had gone despite being there yesterday. After searching yesterday I downloaded some windows updates. Could this account for the disappearace or do you think it looks suspicious?

Although it is gone. There is a still a wrapper.exe listed in the netstats. Is there anyway that you can see what the netstats listing refers to using netstats or otherwise?

Thanks

The problem is that the file itself doesn't come up in searches anymore but there is a wrapper.exe still listed in the netstats. I don't know if this is a virus that is hidden or a valid file that is hidden. I have searched for hidden files.

I was wondering if there was any way that you could trace the origin of the wrapper.exe file listed in netstats. When I do netstat -b it just lists the name of the thing and says local address.

I believe that one is also Good. Reading this explained it to me.
Description of Windows service wrappers

Why does the service wrappers request access to the Internet ?
When a service inside a service wrapper needs to access the network, then has to go through the service wrapper, so the service wrapper becomes the one trying to get access
